The SELECT element denotes a list box or drop-down list. This is an inline element and requires a closing tag.

Using this Element

There are some common properties and collections that apply to all the elements of the document object model, see Common Properties, Methods and Collections for the HTML Elements in Internet Explorer.

This element can be used within a web page with attributes.

This element can be used within scripts where it will have properties, events, methods and collections.

Attributes

The following table shows items that Internet Explorer Embedded supports.

Attribute	Value	Description
ACCESSKEY	0…9, #, *	Gives access or focus to an active HTML element by using a keyboard character.
CLASS		Associates the element with a CSS style.
DISABLED		Disables the element so that it appears dimmed and does not respond to user input.
ID		Uniquely identifies the element within a document.
MULTIPLE		Specifies that multiple items that can be selected.
NAME	String	Specifies a name for the select control, which is submitted (a name or value pair for each selected OPTION element) so that script can reference the control.
ONBLUR		Event that occurs when the select control loses focus by the pointing device or by tabbing navigation.
ONCHANGE		Event that occurs when the select control loses the input focus and its value has been modified since gaining focus.
ONFOCUS		Event that occurs when the select control receives focus by a pointing device or by tabbing navigation.
SIZE	0…#	Specifies the select control size. When the default value 1 is used, a combo box is rendered. For values greater than 1, a list box is rendered

selectedIndex	long	Read/Write	Sets or retrieves the index of the selected option in a SELECT object. This index is 0-based and returns -1 if no items are selected. Setting this property clears any existing selected items. This property is not useful for the SELECT object with the multiple attribute because it returns the index of only the first selected option.
